Which of the following types of hair loss refers to the loss of hair over the entire scalp and body?

1. Alopecia totalis

2. Alopecia areata

3. Alopecia universalis

4. Alopecia androgenetica

The correct answer is: Alopecia universalis

Alopecia universalis is characterized by total hair loss not just limited to the scalp, but also affecting the entire body. This condition typically occurs as a result of an autoimmune response, where the body's immune system mistakenly attacks hair follicles, leading to widespread hair loss. In contrast, alopecia totalis refers specifically to hair loss on the scalp only, while alopecia areata usually involves patchy hair loss that can happen anywhere on the body, but does not cover as extensive an area as universalis. Alopecia androgenetica, commonly known as male or female pattern baldness, primarily affects specific areas of the scalp due to genetic and hormonal factors, rather than resulting in complete hair loss across the entire body. Thus, alopecia universalis is distinct in its scope and impact on both the scalp and body hair.
